POLE-DISCONNEC'TOR.

Specification of Letters Patent.

Patented Dec. 21, 1909.

Application filed July 8, 1909. Serial No. 506,547.

To all whom it may concern:

Be it known that I, JOHN VIET, a citizen of the United States, residingat Ackley, in the county of Hardin, State of Iowa, have invented certainnew and useful Improvements in Pole-Disconnectors; and I do herebydeclare the followin to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to improvements in pole detachers to be employedwith carriages, wagons and the like.

The invention consists essentially in a device for holding the poleconnected with i the vehicle in such position that the same may bereadily disengaged from the vehicle when the animals become frightenedand attempt to bolt. 7

One object is the provision of a means for operating the disconnectingmember within easy reach of the driver.

Another object is the provision of a means for yieldingly holding theparts in engaging position so as to prevent rattling.

With these and other objects in view as will more fully hereinafterappear, the present invention consists in certain novel details ofconstruction and arrangement of parts, hereinafter fully described,illustrated in the accompanying drawings and more particularly pointedout in the appended claims; it being understood that various changes inthe form, proportion, size and minor details of the device may be madewithout departing from the spirit or sacrificing any of the advantagesof the invention.

In. the accompanying drawings forming part of the specification :Figure1 is a plan view of a vehicle and showing my improved device appliedthereto. Fig. 2 is a side elevation of the device and showing the partsin pole releasing position. Fig. 3 is a plan view of the device. Fig. 1is a vertical section taken on the line i4 of Fig. 3. Fig. 5 is asimilar view taken on the line 55 of Fig. 3.

Similar numerals of reference are our ployed todesignate correspondingparts throughout.

As shown in the drawings, the pole is designated by the numeral 5 and isprovided at its rear or engaging end with the usual U shaped extension,the limbs of which are provided with laterally disposed bolts 0. Thedevice for maintaining the pole in engagement with the vehicle consistsof a pair of detachers secured to opposite ends of the vehicle axle;since these members are identical in structure a description of one willbe suflicient. It is to be understood that I am not to be limited tothis particular manner of securing the device, since it will beunderstood, from what will appear later, that the device may be equallyas well secured to other parts of the vehicle.

As shown, each device consists of an elongated bottom plate 7,substantially rectangular in facial contour and cross section andprovided at what will subsequently be termed its rear end with openings8 for the reception of a U shaped clevis by which it is secured to thevehicle axle. Rising from the opposite sides of the plate 7 are thevertical side walls 9 and 10, which are provided at their upper edgesand adjacent their front ends with semi-circular recesses or depressions11. The recesses 11 are directly opposite each other and are ofsufficient depth to seat one of the laterally extending bolts 6 at therear end of the pole 5. Extending parallel with the vehicle axle anddisposed in advance thereof is a shaft 12, the ends of which arejournaled in the side walls 9 and 10.

A lifting dog is designated in general by the numeral 13 and is of awidth to nicely fit between the side walls 9 and 10. The lifting dog isprovided at its rear end with a longitudinal recess extending to a pointadjacent the intermediate portion of the dog. The portions of the rearend on either side of the recess constitute lugs 14: and 15,

which are provided with alining openings for the reception of the shaft12. The openings in the lugs 14 and 15 are of sufficient size to permitthe dog to be rotated on the shaft 12. The opposite or forward endportion of the dog 13 is provided with a horizontally disposed groove orrecess 16 which corresponds in diameter to the recesses or depressionsll of the side walls 9 and 10.

The dog is ofsuch length that the recesses 11 of the side walls will bein alinement with the recess 16 of the dog when the latter is in ahorizontal position, or substantially .6 of the pole the followingconstruction is keyed thereto at a point in advance of the Fig. 1 tothat shown in Fig. 2 and disengaged from the bolt 6.

at right-angles to the shaft 12, as clearly! shown in the drawings.

As before stated, the dog is loosely fitted on one end of the shaft 12and in order that it may be moved with the shaft the followingconstruction is employed: By referring now to Fig. 5 it will be seenthat keyed to that portion of the shaft 12 between the lugs 14 and 15 isa lifting block 17. This member is annular in contour, or substantiallyso, and on its forward side is provided with a socket or recess 18,which straddles the floor of the recess or that portion of the dogdisposed between the lugs 14L and 15. Thus it will be seen when theparts are in position as shown in Fig. 1 that by turning the shaft 12 tothe right, the block 17 will be rotated, whereby the lower side of thewalls of the recess 18 will bear on the dog and lift the outer orrecessed end upwardly and beyond the side walls 9 and 10.

In order that the pole may be prevented from accidental disengagementfrom the frame, a keeper 19 is provided. "This member is pivoted to theouter face of the side wall 10 and adjacent the rear side of the recessor depression 11. The upper "or free end of the lever is provided with aforwardly extending finger 20, which is adapted to bear on that end ofthe bolt 6 of the pole 5 extending beyond the side wall 10, as clearlyshown in Fig. 1.

In order that the keeper 19 may be rocked from its bearing position onthe bolt 6, when the dog is lifted to disengage the bolt employed :--Byreferring now to Figs. 1, 2 and 3 it will be seen that the shaft 12 hasside wall 9 a plate 21. This member is provid'ed on its periphery with aprojection 22, which is disposed, .when the parts are in engagingposition, a trifle in advance of the vertical plane of the shaft 12.Connection between the projection 22 and upper end of the keeper 19 isestablished by means of a link 23, the front end of which is pivoted orotherwise secured to the upper end of the keeper 19, and the oppositeend likewise connected to the outer portion of the projection 22. Thusit will be seen when the shaft is rotated and the lifting dog ooeratedin the manner before described,

that the rotation of the shaft 12 will cause the plate 21 to rotate,whereby the projection 22 will move rearwardly carrying with it the link23 and by virtue of the latters connection with the keeper 19, thelatter will be rocked from the position shown in When the parts are inposition as illustrated in Fig. 1 it is evident that more or lessrattling will occur, owing to the loose engagement of the lifting dogwith the shaft 12; in order to prevent this rattling and at the sametime to provide a means for aiding the dog to return to its normalposition after having been lifted, the following construction isemployed :-By referring now to the drawings it will be seen that risingfrom the central portion of the bottom plate 7 is a vertical post 24,which extends through an opening formed in the middle portion of thelifting dog 13. The upper end of this post extends considerably beyondthe plane of the dog and terminates in a boss or head 25 and encirclingthat portion of the post between the upper side of the dog and lowerside of the head 25 is a coil spring 26, the terminals of which bear onthe head and dog and serve to yieldingly hold the latter in horizontalposition. With this construction it is obvious that the force eX- ertedby the spring on the dog will positively prevent rattling of the partsduring the movement of the vehicle.

In order to positively insure the rotation of the shaft 12 in the"opposite direction after it has been moved to disengaging position andthe pressure thereon released, the

following construction is employed :-By-

referring now to Figs. 1,2 and 3 it will be seen that depending from theshaft 12 and disposed beyond the plate 21 is a hook 27, whlch isarranged at right-angles to the shaft and'terminates at its lower end ina bill 28, and depending from the front axle of the vehicle is a similarhook 29 terminating at its outer end in a bill 30. The hooks 27 and 29lie in parallel planes and connection between the hooks 28 and 30 isestablished by means of a coil spring 31, the opposite ends of which areprovided with eyes for the reception of the bills 28 and 30. Thus itwill be seen when the parts are in position as shown in Fig. 1 and theshaft turned when the force which turned the shaft is withdrawn, thespring 31 will restore the parts to their normal positions.

In order that the shaft may be rotated by the driver a pair of operatinglevers 32 are employed, the lower ends of which are keyed or otherwisesecured to the shaft 12 between the detachers while their upper endsextend through the floor of the vehicle and terminate in crank handles33.

From the foregoing it will be obvious when either crank handle is pulledrearwardly or toward the operator that the shaft will be rotated throughthe lever 32, whereby the lifting dog 13 will bear on the bolt 6 andlift the same clear ofthe depressions 11 and at the same time the keeperwill be rotated from engagement with the bolt, by

prevented. It will be further observed that the device may be applied tothe numerous forms of vehicles now in use.

Having thus described my invention what is claimed as new, is

1. In a pole detacher, a support, a shaft j ournaled in said support,means for turning the shaft, a lifting dog on the shaft, means securedto the shaft for moving the dog, a keeper pivoted to the support and alink connection between the keeper and shaft whereby the keeper is movedsimultaneously with the dog.

2. In a pole detacher, a support, a shaft journaled in said support, akeeper pivoted to the support and disposed in advance of the shaft, aplate keyed to the shaft and a link connection between the free end ofsaid keeper and said plate.

3. In a pole detacher, a frame having vertical side walls provided ontheir upper sides with pole bolt receiving depressions, a shaftjournaled in said frame, a lifting dog having one end combined with theshaft and its opposite end provided with a socket in alinement with thesaid depressions, a keeper pivotally combined with the frame and havinga forwardly projecting finger in a plane with the upper side of thesocket of the lifting dog and means combined with the shaft forsimultaneously moving the socket of the lifting dog out of alinementwith the recess and the keeper out of the plane of the upper side of thesocket.

In testimony whereof, I affix my signature,
